As far as I know you cannot create a new default font for all controls at
once. However, you can change the default font (and alignment, etc.) for
each type of control. Open the toolbox, click the icon for the control, and
click the Properties icon on the toolbar (or click View > Properties from
the menu). Make the desired changes to font, etc. The changes will apply
to new controls. You will need to make similar changes for other controls.
